Description
If this parameter is set to Enable, the inverter shuts down after receiving
the 0% power limit command. If this parameter is set to Disable, the
inverter does not shut down after receiving the 0% power limit command.
Specifies the output upper threshold for the maximum apparent power to
adapt to the capacity requirements of standard and customized inverters.
Specifies the output upper threshold for the maximum active power to adapt
to different market requirements.
Selects a controller vendor.
Specifies the initial energy yield of the inverter. This parameter is used in
inverter replacement scenarios. Set the initial energy yield of the new
inverter to the total energy yield of the old inverter to ensure continuous
statistics of cumulative energy yield.
The standards of certain countries and regions require that the inverter
should not disconnect from the power grid if the power grid experiences a
short-time failure. After the fault is rectified, the inverter output power
needs to be quickly restored.
If this parameter is set to Enable, the buzzer sounds when the DC input
cable is incorrectly connected. If this parameter is set to Disable, the buzzer
does not sound when the DC input cable is incorrectly connected.
LVRT is short for low voltage ride-through. When the grid voltage is
abnormally low for a short time, the inverter cannot disconnect from the
power grid immediately and has to work for some time.
Specifies the threshold for triggering LVRT. The threshold settings should
meet the local grid standard.
During LVRT, the inverter needs to generate reactive power to support the
power grid. This parameter is used to set the reactive power generated by
the inverter.
HVRT is short for high voltage ride-through. When the grid voltage is
abnormally high for a short time, the inverter cannot disconnect from the
power grid immediately and has to work for some time.
Specifies the threshold for triggering HVRT. The threshold settings should
meet the local grid standard.
During HVRT, the inverter needs to generate reactive power to support the
power grid. This parameter is used to set the reactive power generated by
the inverter.
Specifies the LVRT/HVRT recovery threshold.
Specifies whether to shield the undervoltage protection function during
LVRT.
Specifies whether to shield the undervoltage protection function during
LVRT or HVRT.
